Study Notes
Retentive and Active Components of Removable Orthodontic Appliances
- Retentive components help to secure the appliance in the mouth; an example of what is NOT a retentive component is provided in the context.
- Active components actively influence tooth movement; specific examples are given in questions about their roles.
Acrylic Base Plate Function
- The acrylic base plate serves as the foundation of the removable orthodontic appliance, providing structural support and comfort for the wearer.
Anchorage Component
- The anchorage component is crucial for stabilizing the appliance and ensuring that the active elements can effectively move the teeth.
Mesial and Distal Movement
- Mesial movement refers to the movement of teeth toward the midline, while distal movement refers to movement away from the midline in orthodontic settings.
Purpose of Elastics in Orthodontics
- Elastics are used despite their rapid deterioration because they provide necessary force for tooth movement, enhancing treatment efficacy.
- They help in achieving desired tooth alignment and correcting malocclusions through consistent pressure.
Space Creation Alternatives
- While elastics are commonly used, springs may also be employed to create space within the dental arch, offering alternative methods for managing tooth positioning.
Disadvantages of Elastics
- A primary disadvantage of using elastics with removable appliances is their tendency to wear out quickly, requiring frequent replacement and potentially disrupting treatment progress.
Functions of Active Removable Appliances
- Active removable orthodontic appliances are designed to actively shift teeth into proper alignment, utilizing various components to exert controlled forces.
